Based on above-described embodiment, introduce an application example of the present invention, relate to client (hereinafter referred to as STA) and the access point (hereinafter referred to as AP) of WLAN, STA is as WLAN work station, comprise 802.11 functions, AP is responsible for the access service providing WLAN, can shared network to STA.
In this application example, the access point broadcast that access point sends still adopts Beacon frame of the prior art, comprising the title of access point, the MAC Address etc. of access point, and the response message that the connection message that access point sends, client send and client broadcast message all adopt is expansion management frame in 802.11 agreements.
As shown in Figure 10, wherein this two hop counts value of subtype subtype value 0110 ~ 0111 and 1110 ~ 1111 of management frames retains and not yet uses management frame format in 802.11 agreements at present, and the embodiment of the present invention can use it as expansion type.
In frame main body Frame Body, we can add the information element informationelement of our needs.So-called information element, refers to the block of indefinite length.Each block all can mark type number and size, and the data bit of various information element has specific interpretive mode.
The response message that client sends, subtype value 1110 can be used as the acknowledgement frame type of Beacon, DA(Destination Address, destination address) and BSSID(Basic Service Set Identifier, basic service set identification code) be filled to the MAC Address of the access point sending Beacon frame, SA(SourceAddress, source address) fill the MAC Address of client, according to the standard of 802.11 agreements, the information element such as the title of access point and the transmission rate of client support can be added in Frame Body.
The connection message that access point sends, subtype value 1111 can be used as the connection frame type of access point, DA fills the MAC Address of the client that will send to, the MAC Address of SA populating access point, BSSID fills the MAC Address with the access point of same networking belonging to current access point, when access point reaches maximum load, BSSID is the MAC Address of other idle access points in same ESSID or same WDS.According to the standard of 802.11 agreements, the information elements such as the title of access point, cipher mode and key can be added in Frame Body.Now, the title of what the title of access point was corresponding the is access point inserting BSSID.
Client broadcast message, can use subtype value 0111 as the broadcast frame type of client, and DA fills complete 1, SA fills the MAC Address of client, BSSID fills complete 1, according to the standard of 802.11 agreements, can add the transmission rate that client is supported in Frame Body.
As shown in figure 11, the STA workflow of this application example is as follows:
Step S1, STA monitor air message of eating dishes without rice or wine, and wait for the arrival of the Beacon frame that AP sends.
Step S2, STA receive Beacon frame, resolved, and preserve resolving information by frame parsing module.
Step S3, STA carry out the filling of Beacon acknowledgement frame by frame expansion module according to resolving information.
Step S4, if STA have received the AP connection frame that AP sends, is then resolved by frame parsing module, proceeds to next step; Otherwise process terminates.
Step S5, STA go to connect AP according to the AP link information parsed.
As shown in figure 12, the AP workflow of this application example is as follows:
Step C1, AP ceaselessly send Beacon frame at a certain time interval, the existence of declaration itself.
Step C2, after AP receives Beacon acknowledgement frame, is resolved by frame parsing module.
Step C3, carries out by frame expansion module the filling that AP is connected frame according to the loading level of the information and the AP that resolve.
Step C4, send AP to STA and connect frame, process terminates.
It should be noted that, when AP meet the requirements of load capacity namely do not allow unnecessary STA access time, it can be other AP information in same ESSID or WDS that AP connects the APN of frame and BSSID.
In sum, the WLAN networking mode that the embodiment of the present invention proposes and system, by use the mode of expansion management frame realize AP find STA and and STA carry out the function of link information transmission, reaching can the connection of direct control STA at AP end, user is direct by this method can carry out networking fast at AP end, achieve certainly being dynamically connected of STA end, avoid some misoperations of user, also can when AP end reaches maximum load, allow STA be connected to the AP of other resources free time, the network facilitating user to realize WLAN is shared.
By the explanation of embodiment, should to the present invention for the technological means reaching predetermined object and take and effect be able to more deeply and concrete understanding, but appended diagram be only to provide with reference to and the use of explanation, be not used for being limited the present invention.
